Practice - 5 Tasks

1fill in blank

💡 Hint

Common Mistakes

Using minimize() instead of maximize()

Using setSize() without parameters

The maximize() method maximizes the browser window to full screen.

2fill in blank

medium

Complete the code to get the current size of the browser window.

Selenium Java

Dimension size = driver.manage().window().[1]();

Drag options to blanks, or click blank then click option'

BsetSize

CgetSize

DgetPosition

💡 Hint

Common Mistakes

Using setSize() instead of getSize()

Using getPosition() which returns window location

The getSize() method returns the current size of the browser window as a Dimension object.

3fill in blank

hard

Fix the error in setting the browser window size to 1024x768.

Selenium Java

driver.manage().window().setSize(new Dimension([1], 768));

Drag options to blanks, or click blank then click option'

A1024

B768

Cwidth

Dheight

Attempts:

💡 Hint

Common Mistakes

Using height instead of width as first parameter

Using 768 as width instead of height

The Dimension constructor takes width first, so 1024 is the width.

4fill in blank

hard

Fill both blanks to set the browser window size to 800x600.

Selenium Java

driver.manage().window().setSize(new Dimension([1], [2]));

Drag options to blanks, or click blank then click option'

A800

B600

C1024

D768

Attempts:

3 left

💡 Hint

Common Mistakes

Swapping width and height values

Using incorrect numbers like 1024 or 768

The Dimension constructor takes width first (800), then height (600).

5fill in blank

hard

Fill all three blanks to maximize the window, get its size, and print width.

Selenium Java

driver.manage().window().[1]();
Dimension size = driver.manage().window().[2]();
System.out.println(size.[3]());

Drag options to blanks, or click blank then click option'

Amaximize

BgetSize

CgetWidth

DgetHeight

Attempts:

💡 Hint

Common Mistakes

Using getHeight instead of getWidth

Forgetting to maximize before getting size

First, maximize the window with maximize(). Then get the size with getSize(). Finally, print the width using getWidth method of Dimension.

Practice

1. What does the maximize() method do in Selenium WebDriver window management?

easy

A. It retrieves the current size of the browser window.

B. It makes the browser window fill the entire screen.

C. It sets the browser window to a custom size.

D. It closes the browser window.

Solution

1. Step 1: Understand the purpose of maximize()

   The maximize() method is used to enlarge the browser window to fill the entire screen.

2. Step 2: Differentiate from other window methods

   Unlike setSize() which sets a custom size, maximize() fills the screen automatically.

3. Final Answer:

   It makes the browser window fill the entire screen. -> Option B

4. Quick Check:

   maximize() = fills screen [OK]

Hint: maximize() fills the screen fully, setSize() sets custom size [OK]

Common Mistakes:

• Confusing maximize() with setSize()
• Thinking maximize() returns window size
• Assuming maximize() closes the window

2. Which of the following is the correct syntax to set the browser window size to 1024x768 in Selenium Java?

easy

A. driver.manage().window().maximize(1024, 768);

B. driver.window().setSize(1024, 768);

C. driver.setSize(1024, 768);

D. driver.manage().window().setSize(new Dimension(1024, 768));

Solution

1. Step 1: Recall correct method to set window size

   In Selenium Java, setSize() requires a Dimension object with width and height.

2. Step 2: Check syntax correctness

   driver.manage().window().setSize(new Dimension(1024, 768)); correctly uses driver.manage().window().setSize(new Dimension(1024, 768));. Other options misuse method names or parameters.

3. Final Answer:

   driver.manage().window().setSize(new Dimension(1024, 768)); -> Option D

4. Quick Check:

   setSize() needs Dimension object [OK]

Hint: Use new Dimension(width, height) inside setSize() [OK]

Common Mistakes:

• Calling maximize() with parameters
• Using setSize() without Dimension object
• Wrong method chaining like driver.window()

3. What will be the output of the following code snippet?

driver.manage().window().setSize(new Dimension(800, 600));
Dimension size = driver.manage().window().getSize();
System.out.println(size.getWidth() + "," + size.getHeight());

medium

A. 800,600

B. 600,800

C. 0,0

D. Throws a runtime exception

Solution

1. Step 1: Set window size to 800x600

   The code sets the browser window size to width=800 and height=600 using setSize().

2. Step 2: Retrieve and print the window size

   The getSize() method returns the current size, which is then printed as "width,height".

3. Final Answer:

   800,600 -> Option A

4. Quick Check:

   setSize(800,600) then getSize() = 800,600 [OK]

Hint: getSize() returns current size after setSize() [OK]

Common Mistakes:

• Mixing width and height order
• Expecting maximize() effect instead
• Assuming getSize() returns null or error

4. Identify the error in the following Selenium Java code snippet for setting window size:

driver.manage().window().setSize(1024, 768);

medium

A. The method name should be setWindowSize(), not setSize().

B. setSize() cannot be called on driver.manage().window().

C. setSize() requires a Dimension object, not two integers.

D. The code is correct and will run without errors.

Solution

1. Step 1: Check setSize() method parameters

   The setSize() method requires a single Dimension object, not two separate integers.

2. Step 2: Identify the error cause

   Passing two integers directly causes a compile-time error because no matching method exists.

3. Final Answer:

   setSize() requires a Dimension object, not two integers. -> Option C

4. Quick Check:

   setSize() needs Dimension object [OK]

Hint: Always wrap width and height in new Dimension() for setSize() [OK]

Common Mistakes:

• Passing width and height as separate arguments
• Using wrong method name
• Ignoring compile-time errors

5. You want to maximize the browser window and then verify if the window width is greater than 1200 pixels. Which code snippet correctly performs this check in Selenium Java?

hard

A. driver.manage().window().maximize();
Dimension size = driver.manage().window().getSize();
if (size.getWidth() > 1200) {
System.out.println("Width is greater than 1200");
}

B. driver.manage().window().setSize(new Dimension(1200, 800));
Dimension size = driver.manage().window().getSize();
if (size.getWidth() > 1200) {
System.out.println("Width is greater than 1200");
}

C. driver.manage().window().maximize(1200, 800);
Dimension size = driver.manage().window().getSize();
if (size.getWidth() > 1200) {
System.out.println("Width is greater than 1200");
}

D. driver.manage().window().maximize();
Dimension size = driver.manage().window().getSize();
if (size.getHeight() > 1200) {
System.out.println("Width is greater than 1200");
}

Solution

1. Step 1: Maximize the browser window

   Use maximize() without parameters to fill the screen.

2. Step 2: Get window size and check width

   Retrieve size with getSize() and compare width with 1200 pixels.

3. Step 3: Verify correctness of condition and output

   driver.manage().window().maximize(); Dimension size = driver.manage().window().getSize(); if (size.getWidth() > 1200) { System.out.println("Width is greater than 1200"); } correctly checks width > 1200 and prints the message.

4. Final Answer:

   Option A code snippet correctly maximizes and checks width. -> Option A

5. Quick Check:

   maximize() then getSize().getWidth() > 1200 [OK]

Hint: maximize() no params; getSize() then check width [OK]

Common Mistakes:

• Passing parameters to maximize()
• Checking height instead of width
• Using setSize() instead of maximize() for full screen
